Lab Bread Board System Trainers is a "6 in 1" system. It provides regulated power supply and input signals, which are most widely used.

1. DC POWER SUPPLIES:
It has three IC-Regulated power supplies:

• a. +1.2V to +15V/500mA (Variable)
  
• b. -1.2V to -15V/500mA (Variable)
  For energising NPN, PNP transistors, op-amps & linear ICs.
  
• c. +5V (fixed) / 1A (for Digital ICs)

2. AC POWER SUPPLY: It has a centre tapped (15-0-15)V power transformer to conduct half wave , full wave bridge rectifier and voltage multipliers.

3. SINE/SQUARE WAVE SIGNAL GENERATOR: It has two signal sources (i.e.). Sine wave and square wave. It is intended primarily to test and measure audio equipment parameters such as input sensitivity, frequency response, stage gain, distortion and power.
The sine/square generator is completely an IC version and generates frequencies from 2Hz to 200KHz in 5 decade ranges.

FREQUENCY SELECTOR:

AMPLITUDE CONTROL: Amplitude varies from (0 - 10)V Peak to Peak.
FUNCTION SELECTOR: To select either sine wave or square wave.

4. CLOCK GENERATOR : It has TTL compatible clock generator of exactly 1Hz (One Second Signal) energising frequency counters.
5. POTENTIOMETERS like 1K, 5K, 10K, 50K, 100K, 470K are provided.
6. LAB BREAD BOARD SYSTEM trainer is provided with 2 bread boards to construct various circuit with the help of various inputs and outputs provided in this trainer.
